An Aspirin a day keeps the flowers on display! Question:
What is the best way to keep cut flowers fresh the longest? Hypothesis:
If cut flowers are placed in Aspirin water then they should stay alive longer then in any other type of water. Research:

http://www.gardeningknowhow.com/flower/how-to-keep-flowers-fresh-after-cutting.htm Results:

Trial 1:
Aspirin water: lasted almost 9 days. Wilted on day 8 at 10:35 PM
Sugar water: lasted 6 days. Wilted on day 6 at 11 AM
Penny water: lasted 7 days. Wilted on day 7 at 12:15 AM
Warm water: lasted 5 days. Wilted on day 5 at 10:30 AM

Trial 2:
Aspirin water: lasted 8 days. Wilted on day 8 at 1 PM
Sugar water: lasted 6 days. Wilted on day 6 at 11:30 AM
Penny water: lasted 7 days. Wilted on day 7 at 11 AM
Warm water: lasted 5 days. Wilted on day 5 at 12 AM

Trial 3:
Aspirin water: lasted almost 9 days. Wilted on day 8 at 10:50 PM
Sugar water: lasted 6 and a half days. Wilted on day 7 at 7 AM
Penny water: lasted 7 days. Wilted on day 7 at 1 PM
Warm water: lasted 5 days. Wilted on day 5 at 12 AM Conclusion:
The test results supported the hypothesis. The flower in the Aspirin water lasted on average 8 days. It lasted longer than the other types of water. The sugar water lasted 6 days, the penny water lasted 7 days and the warm water lasted 5 days.
Some other experiments that could be formed from this experiment may be “What is in Aspirin water that helps flowers stay fresh longer?” or “Does Aspirin water only help certain flowers?” No problems formed during the experiment that could have affected the test results.
This information could be beneficial to florist. This could help them keep their flowers fresh longer so that they last long enough to sell. This information could also help people who want to keep flowers in their house. It can help them keep them fresh longer so that they don’t have to spend money and buy flowers as often. materials and Procedures:
Step 1: get 4 cups
Step 2: get a penny
Step 3: get an aspirin
Step 4: get sugar
Step 5: put four flowers in a different cup
Step 6: Watch to see which flower dies first
12 freshly cut flowers
put 4 flowers in the four various cups and leave them. Log progress throughout 10 days. Repeat experiment 2 more times. Abstract:
The purpose of my science fair experiment was to see which method worked best to keep fresh cut flowers fresh the longest.
I predicted that if cut flowers are place in Aspirin water, then they should stay alive longer than any other type of water.
For the procedures you need a penny, an Aspirin, sugar, and warm water. Then you need to place them all in a cup with room temperature water (except the warm water) and log process throughout 3 days.
The warm water flowers only lasted 5 days when the Aspirin water lasted almost 9 days. The Sugar water and penny water were neck in neck but the penny water lasted 7 days when the sugar water only lasted 6 days.
The test results supported the hypothesis. The Aspirin water lasted on average 8 days while the others didn’t last that long. This proves that Aspirin water keeps freshly cut flowers fresh the longest. Asprin Water Sugur Water Copper Water Warm Water
Trial 1 9 Days 6 Days 7 Days 5 Days
Trial 2 8 Days 6 Days 7 Days 5 Days
Trial 3 9 Days 6.5 Days 7 Days 5 Days
